Diamond segment is welded to saw blank with high-frequency welding machine. Since diamond segment and saw blank made of different metal, we adopt this brazing welding technique.
Process:
First, Diamond segment ground and polished by grinding wheel
Second, put silver soldering piece( silver-plated copper piece) between the diamond segment and saw blank
Third , turn on the high-frequency welding machine to achieve water and high temperature
Last, weld the diamond segment and saw blank together.
Notice:
1) Choose proper diamond segment according to the cutting material. Quality of diamond segment determine the cutting efficiency and lifespan of the saw blank. The technique should allow timely adjustment of diamond segment to make sure accurate welding.
2) Choose proper sliver soldering piece, silver content no less than 35%. pay attention to the welding temperature and time. Welding temperature should be set 600℃-800℃. too high temperature and too long period will make adjacent teeth stick together, then whole diamond saw blade deform. Isolation welding and diagonal welding is highly suggested to avoid the deformation of the saw blank.
3) Diamond saw blade should be naturally cooled on the welding frame for at least 2 hours before removed after welding process. Then the diamond saw blade should be hung vertically. Generally speaking, diamond saw blade can be put into use after 10-hour hanging.
